Lindstrom continues to wait for MRI results

BALTIMORE -- Orioles reliever Matt Lindstrom could not hide his disappointment on Saturday, one day after the Orioles placed him on the 15-day disabled list with an injury to his right middle finger.

The right-hander said he hurt the finger during the previous series against Texas. The Orioles are still waiting for a definitive diagnosis on the extent of the injury. Lindstrom has a 1.29 ERA with 14 strikeouts in 13 appearances.

"It was the third or fourth outing against Texas when I felt kind of a pop or something like that. I didn't know what it was," Lindstrom said. "When your adrenaline is going like that, you usually just disregard something like that unless it's something real serious. It wasn't really affecting me. I did my normal workout routine and I woke up the next morning and it was pretty stiff. I talked to the doctor and he advised me, I should get it looked at for down the road."

The Orioles are hoping there is not significant ligament damage that might shut Lindstrom down for an extended period. Lindstrom tried to remain optimistic it's a minor injury.

"Who knows?" Lindstrom said. "It could just be a sprained knuckle. Hopefully, it's nothing big. It's something that is kind of unexpected and unfortunate."

Orioles manager Buck Showalter was also anxiously awaiting word on the prognosis.

"We got the MRI back, but finding somebody to read it might have to wait until Monday," Showalter said.

Hall ready to play all over for Orioles

BALTIMORE -- Utility man Bill Hall was in Baltimore and starting in left field for Saturday's game against Tampa Bay after the Orioles purchased his contract from Triple-A Norfolk.

Hall homered in the eighth inning as the O's beat the Rays, 5-3.

Hall signed a Minor-League deal with the club after failing to make the Yankees' 25-man roster out of Spring Training. Hall's line was .222/.269/.281 with two home runs and seven RBIs in 15 games with Norfolk. While the 32-year-old Hall usually plays third base, the Orioles will look to utilize his versatility, according to manager Buck Showalter.

"I have always had that mentality of moving around and doing whatever I needed to do to help the team win," said Hall, who hit seventh against the Rays. "I don't think that's ever gonna change, no matter how old I get. I feel like you put me anywhere on the field and I'm not going to embarrass us. Hopefully, I'll be better than average. That adds a lot of versatility to me. Obviously, that is a good thing."

Hall also was excited to join a first-place team and he was impressed by the way the Orioles have battled through numerous injuries this season. He had no concerns about adjusting to the outfield.

"I've been watching all along," Hall said about the big league club. "They got off to a great start and they've been maintaining it. This team has stayed consistent throughout. I'm very excited to be a part of that and add something to it in some ways."

With the addition of Hall to the 40-man roster, the Orioles designated pitcher Brad Bergesen for assignment. Bergesen, a fourth-round pick by the Orioles in 2004, is 1-2 with a 5.13 ERA in eight games for the Tide.

Wieters gets start at DH after collision

BALTIMORE -- Matt Wieters started at designated hitter Saturday after being involved in a violent collision at the plate with Sean Rodriguez on Friday.

Given that Wieters caught Thursday and Friday and the Orioles play at 1:35 p.m. ET on Sunday, manager Buck Showalter said Wieters likely would have been Saturday's designated hitter either way. Still, Friday's play was a factor in the decision.

"I was leaning towards DHing him today because of the day game the next game," Showalter said. "But the collision solidified that leaning."

In the fourth inning of Friday's 4-3 win, Elliot Johnson singled off the wall in right, scoring Matt Joyce and prompting Rodriguez to try to score from second. Nick Markakis made the relay to Robert Andino, who fired the ball to Wieters at home.

Andino's throw put Wieters in a great position to block the plate, giving Rodriguez no other choice but to try to go through him. Rodriguez lowered his shoulder and plowed into Wieters while also delivering an elbow to Wieters' jaw, but the catcher held on to record the out.

"He came in hard, but I felt OK," Wieters said after the game. "Everything was fine the whole way. I bit my lip, and that was about the worst of it."

Luis Exposito made his third start of the season in Wieters' place on Saturday.
